IMPROVEMENT IN CARPET-BEATERS.

Specification forming part of Letters Patent No. 139,145, dated May 20, 1873; application tiled April 25, 1873.

To all whom it may concern:

Be it known that I, WILLIAM H. HANKIN- soN, of the city, county, and State of New York, have invented an Improved Carpet- Beating Machine, of which the following is a specification:

The object of my invention is to produce a machine which will clean carpets throughout their whole width by means of rigid links fastened to a horizontal shaft, and having their beating-surfaces parallel to the axis of such shaft, or nearly so.

A machine thus arranged will possess several advantages over the ordinary system of straps or whips, in that the entire width of the carpets can be reached by the links, while the. straps or whips, being usually at right angles to the shaft, could only clean those certain portions of the fabric which they happened to strike, and if not arranged very close together would clean the carpet but very imperfectly.

It had been supposed that rigid links would do greater injury to the carpets than the straps or whips; but I have found that if properly smoothened they are more effective than dexible and coarsely-surfaced beaters, and less liable to injure the fabrics.

the carpet is to be cleaned is stretched, and by which it is fed. C represents a horizontal shaft, hung in the frame A parallel to the drums B. The shaft is connected by means i of gear-wheels a a, or otherwise, to a drivingi shaft, E, so that rapid rotary motion may be imparted to it. The driving-shaft E may be driven by steam or-muscular power. The

shaft 0 is provided with a series of radiating` arms, f f, always arranged in pairs. They are applied along the en tire length of the shaft C, dividing it into three, more or less, sec- I tions longitudinally. I prefer to arrange the arms ff, of which there are several pairs in each section, at such different angles to each other that the beaters suspended from them will strike the carpet at dii'erent times, but` successively. To each pair of arms f f are jointed the ends of U-sha-ped beaters g g g, made. of ordinary gas-pipe or of other suitable tubular or solid inexible material-either metal, wood, or bothwhich will, when moi tion is imparted to the driving-shaft E, strike the carpet, while it is fed along the drums, and clean it. There being thus a series of beaters.

g, applied around the shaft C at every part of y its circumference, it is clear that the carpet will at every revolution of the shaft be struck several times, and, therefore, thoroughly beat- I en and cleaned.

I claim as my invention and desire to se-` radial arms f of the rotary shaft C, substantially as speeilied.
